Again poor use of old aircraft and old business class seats that show there age.

Service and food were very good, I liked it a lot. I liked the little gifts we all got , but I don’t think I’d fly on Turkish airlines to go to New York from Istanbul or from New York to Instanbul anymore. Flight is way too long.

We liked the comfort and seats. The crew was not very friendly nor did they check on us to see if we needed anything. Had to ask for water several times

The rules regarding business class lounge hotel/room access were very confusing. Between flights we had an 11 hour layover in Istanbul, but were denied a room to rest as our layover was too long?? Keep in mind that we arrived there at 3:30am after a long flight. Even multiple Turkish airlines employees were inconsistent with the rules. We ended up paying a high price at the Yotel in the airport in order to get some rest. Good thing I did, as a medical emergency was declared on the flight from Istanbul to Atlanta and I was apparently the only physician on board. Luckily I was able to stabilize the passenger and the flight wasn't diverted. The crew called an overhead announcement for a medical doctor, but insisted that I show them a copy of my medical license which I did. Very strange in my 35 years as a physician and responding multiple times to inflight medical emergencies over the years. I was very glad the passengers issue was resolved, but an acknowledgement of at least a thank you from the crew would have been appreciated.

I wasn't able to bring my little dog with me, because of the feedback team's extremely slow response. How are they even allowed to operate with this paste??

The sleeper seats, the staff, and the food was truly delicious. I loved the mocktail options.

Great service. Seat was a bit small but it was fine. Food was great

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

I liked the flight, the attendants, and the comfort. But the gate for boarding was poor. Even the elderly had to climb down many many steps to the bus and climb up to the plane.

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

Lufthansa is turning into a budget airline. On transfers, the luggage never arrives if you have less than 2 hours for the transfer. This is happened to me multiple times when I end up on flights serviced by Lufthansa. The first leg of the flight was serviced by Discover Airlines. It was a 3-hour flight and they only offer a glass of water. Everything else is for purchase. I purchased my ticket as economy which should have included a bag but it ended up booking as economy light so I had to pay for a bag in each direction.

The food that was served was superb!!! Awesome snacks!!! Frequent drink service!!! To me, this was shocking. I took a British Airways flight from Denver to London for the first leg of my trip and the food was horrendous. Thank you for keeping us fed and satiated on such a long flight!!!!

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.

My flight was delayed d the gate was never updated inside the terminal. If I hadn’t checked my email I would have missed my flight. Also, I paid a total of $5100 for my flight to be. Business or first class. My final leg of my flight from Heathrow to Frankfurt was not to standard of what I expected or experienced in the previous legs of my trip.

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

I think it was a United A380 plane. The trip from Munich to Denver was about 12 hours and the preferred economy seat I paid $75 for was very cramped. The crew was nice but I was so uncomfortable and getting up to walk around didn’t really help. My legs were swollen for 4 days afterward. I would think on such a long trip the seats would have more room. I would have gone 1st class but it was 3-4 times more expensive. I won’t fly anywhere far away again. My last experience with Lufthansa was great to Italy and back, but this time I could swear everything was United and not good.

Not good. They charged an additional $70 to check a bag we had already paid for on line with Lufstansa

This flight went smoothly and the economy plus free upgrade worked very well.
